Ideal for water quality

 

Fluoride is one of the very few chemicals that have been shown to cause significant effects in people through drinking-water. Fluoride has beneficial effects on teeth at low concentrations in drinking-water, but excessive exposure to fluoride in drinking-water, or in combination with exposure to fluoride from other sources, can give rise to a number of adverse effects.

Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay. Fluoridated water operates on tooth surfaces: in the mouth it creates low levels of fluoride in saliva, which reduces the rate at which tooth enamel demineralizes and increases the rate at which it remineralizes in the early stages of cavities.

A 1994 World Health Organization expert committee suggested a level of fluoride from 0.5 to 1.0 mg/L, depending on climate. Bottled water typically has unknown fluoride levels, and some domestic water filters remove some or all fluoride.

The HI 729 Checker®HC is simple to use. For this measurement you need 2 vials (#1 and #2); in both vials add 2 mL of reagent and until the mark: deionized water in vial #1 and sample in vial #2, and gently invert 5 times, and wait 2 minutes. Then insert the cuvette #1 into the HI 729 Checker®HC and press the button to zero; after that cuvette #2 to read the measurement results.

Order Information:

HI 729 Checker®HC is supplied with sample cuvettes with caps (2), reagents for 6 tests, syringe with tip, battery and instructions.
